CD74HCT4514E datasheet by Texas Instruments

CD74HCT4514E Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HCT4514E can handle?
  The CD74HCT4514E can handle clock frequencies up to 25 MHz.
• How do I ensure that the CD74HCT4514E is properly powered?
  The CD74HCT4514E requires a power supply voltage (VCC) of 4.5V to 5.5V, and it is recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to ensure proper power supply decoupling.
• What is the maximum current that the CD74HCT4514E can sink or source?
  The CD74HCT4514E can sink or source up to 6mA of current per output pin.
• How do I handle the asynchronous reset input (MR) of the CD74HCT4514E?
  The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor (e.g. 1kΩ) to ensure that the device is properly reset. A low-going pulse on the MR input will reset the device.
• Can I use the CD74HCT4514E in a 3.3V system?
  Yes, the CD74HCT4514E can operate at 3.3V, but the output voltage levels will be reduced accordingly. It is recommended to use a voltage regulator to ensure a stable 3.3V supply.
